I'm 36 and have been lucky enough to have owned in recent years - Civic type r, Leon cupra r, alfa 147 1.9 jtd multijet and most recent a Renault megane renaultsport 225.
I have just brought a GT jtdm lusso 07 with leather, winter pack, reversing sensors, 18 " alloys, bose speaker upgrade, kenwood dnx 5220 sat nav/dvd/ipod touch screen built in with 29k on the clock for £11200.
When i sold the renault i was worried i'd miss the raw power and acceleration. The megane was by far the best of the bunch imo of the hot hatches.
I'm pleased to say the Alfa's plus points have made me forget about the renault already. It really has impressed on all levels. The torque is amazing and smooth isn't the word, i feel i could drive it all over the country without wanting to get out, it really does stand up to the 'Grand tourer' label. If i have one gripe its how high the body is, i've got 18" alloys and the wheel arch gap is massive, doesn't look half low enough in my opinion -prehaps a bit to anal but i am considering having it lowered to make me completly satisfied.
Only owned her two weeks, but feel the honeymoon period will last for a long while with this one. Also, on the fuel economy side i am getting 40 -50 mpg all the while which is amazing for the power you have under your right foot.
The 150 bhp is much more responsive than the 140 that i had in the 147. 10bhp seems to make a lot of difference.
Hope you are enjoying as much as i am!!
