Im 25 and have had a little 316 petrol (bless her), 318 petrol, 320 diesel and now a 335 diesel.
I'm a lazy person so i love my diesels. Maybe not the best sound but its still nice enough for me. Up to 49mpg on motorways @ 70mph and the potential to go even faster with a tune. So i'd choose my current car and the money saved on all my costs paid, i'd go modding crazy
