mk tdi, pd130, is an ace car. I learnt to drive in it with my dad, and when i went back to the 1.2 corsa i took my test in i nearly cried. the tdi is a beasty car and will smoke most cars off the lights, not that ive tried, and will give you a steady 40mpg, if you drive like a twit like me. other than that my dad got it cuz he does a lot of miles and also likes his speed, although he wont admit it. the gt tdi would be my ideal car, but its a little bit more expensive than the 130 brake tdi. ecu remaps are fairly cheap for good power increase and increases in mpg's. about £500 for an AMD remap on an RR giving +30 brake and +30 lbs. or go for £2250 stage 3, + 55 brake and + 75 lbs, and an exhaust with turbo remap. what'll kill you though is the f**king torque, they pull like a f**king elephant on crack, hard to change gears quickly enough, for me anyway. buy one, 150 brake, remap it then go rip it up. then add an extra turbo, intercooler, etc etc. go for it!!!
