Hi Mysterio, where in Dub are you? I'm in Tallaght. Welcome to the forum. First off for the sheer enjoyment you will get from your Alfa you wont regret any faults you may come across. Trust me.
If I where you, and I'm not, I would get myself a 146 as there is some very good quality ones out there. And they are mostly 1.4 so insurance and tax will be cheaper. They are a good car, Damien will confirm that wont you Damien
Then when you have been truly bitten by the bug you can upgrade to something bigger when your ready like a 147 156 166 8C
Furthermore and this is important you will have ample cash left over to spend on any repairs it might need. If buying from a garage it will have the basics done but may need a tbelt but I go for private sales for all my cars as you can bargain them down further i find. Also you can put some of that left over cash to tax and insurance.
Regarding insurance I'm afraid I'm useless, I just go with broker but probably should shop around, I'm just lazy about that.
If your going to look at a car I'll tag along as long as I'm free. I suppose if the dealer see's us all pulling into his forecourt in Alfas he will know he cant try and pull the wool over your eyes. All that said between everybody here we have enogh know how to help you along so get out and get yourself a true drivers car.
