Well chaps, here are my impressions.
Summary

'nuff said.
I test drove a white Gallardo at lunch time. Let me tell you something: for who know me, I don't skip lunch. And if I have to, then I am a miserable git for the rest of the day. I skipped lunch to test drive the car and I am still high, with a huge grin on my face. Yeah, like this
I drove in Tokyo, which is not very conducive to really test the car but my 40 minutes or so of driving were, well, inspirational. Yes, they inspired me to work harder (ie. there goes my postcount

) and be able to afford one of these cars.
The car had 5,500 km on the clock with e-gear (Lambo's version of the selespeed gearbox) and the salesguy mentioned that it had been treated fairly roughly.
Anyway, I'll try to breakdown the features of the car.
Exteriors
Although the Murcielago is more menacing, the Gallardo is very beautiful. In pearly white, it looked perfect despite the slightly dodgy yellow calipers (not really looking good on a white car).
The car looks very well proportioned with minimal overhang. The rear spoiler is small and tasty (almost unnoticeable) and the wheels pretty, though I think a car this size needs 20'' wheels, though it only comes with 19''.
The rear exhausts look a little pudgy (!?) but the front and back grill are very cool, they sort of give the car a stealthish look.
It's a shame it's got regular doors (not scissor ones) and no keyless entry but other than that, it's got looks that I can't fault at all. Oh, it doesn't have a start button, but frankly I do think these start buttons are too gimmicky.
Interiors
Well, to be honest, I was expecting something better. I know that Lambo is not a luxury carmaker but a sports-car maker but darn it, the indicator stalk was made of plastic so cheap, I felt it was about to break. Generally the switchgear is subpar as so is the dealer fitted SatNav and the standard stereo. Of course, we all want to hear the engine rather than music but then why bother at all with one?
The seats are comfy and hold you quite well but the ones in my GranSport are better, believe it or not. The roof is quite low and as a consequence headroom is limited but I am short (5'.6'') so that works fine for me. The one odd thing was the position of the pedals: completely to the right and I almost had to sit sideways. What's up with that?
The steering wheel's shape is sporty, with the bottom bit flat. It feels of the right size and grips well. The e-gear stalks are also cheapish, feel flimsy and are odd looking (with long narrow beams coming out of the steering wheel block), I'd rather have the ones in the GranSport anyway.
Engine
This car has 520hp and 510Nm of torque, of course the engine is a monster. The noise is amazing.
I mean, how can I possibly describe this powerplant?
Handling
The only thing I could do with the car is drive it in the city, so it's hard to say anything particularly meaningful. When pressing the throttle a little, I felt the car to be very stable and could hold it easily in its lane. The balance is 42% front and 58% back, and I am too inexperienced to tell you if the car oversteers or not, but it just felt good.
This type of car obviously doesn't like rough surfaces and upon braking, I felt some torque steer (which for a AWD car is a bit odd I'd think). I wonder how it would react under heavy braking.
I couldn't really test the brakes but the car had the steel Brembos with 8 pots at the front and 4 at the back. Never felt they wouldn't be able to do the job but there was simply no chance to find out.
Gearbox
I tried the e-gear in auto mode, manual mode and sport mode. As a sidenote, the sport mode in this car only changes the speed of the shifts (no change in suspensions or engine settings) so I am not really sure why they bothered even having a sport mode.
At low RPMs, the car stutters a bit too much (salesguy said it was because it was a test car and had been driven hard, but I don't quite believe him) and you cannot quite do anything about it but try to be super smooth with the throttle.
The auto mode is alright but sluggish, as you'd expect it to be and frankly probably something you should never use as this car requires complete control over it. I just wouldn't let the computer do all the thinking for me.
Even in manual mode, the car dowshifts by itself. However, I felt the downshifts are not as well calibrated as the ones in my GranSport, they sort of seem to happen too late, leaving you in a taller gear than you'd want.
So in essence, the overall transmission was ok (my expectations were low after reading the e-gear reviews on the web) but not spectacular.
Conclusion
I was honestly surprised by how easy it was to drive this car. I grew up with a poster of the Countach in my room (well not quite, as I never had my own room, but you know what I mean) which was famous for being nearly undrivable. Well, the Gallardo is a car that can really be driven by almost anyone.
The car is truly spectacular, with sheer power being the defining characteristic of this monster. But the looks are also extremely attractive: suffice to say for the first time in my life I saw someone whip out a camera and take a picture of me (well, the car really) whilst I was at a red light.
Post Scriptum
Whilst pulling out a red light, I moderately pushed the car (I mean, very gently) at which point some guy with an Impreza or whatnot tried to keep up. All I had to do is push the throttle down a little bit (honestly, just a tad) and the whole world became a blur. I mean, the car just took off like a friggin' rocket
That's all folks
