I love my MK1 Ph3. She's the most basic model they did with no extras but doesn't matter.
Bought her 2.5years ago with 38,000 miles and 2 previous owners.
She now has just over 80,100 miles on her, over 40,000 of (almost) trouble free motoring!
Only trouble I've ever had with her is the exhaust, had to replace all but the cat in the first year which wasn't particularly expensive at the time. (£50 ish for the back box and middle pipe and £<50 for the down pipe some months later) This week its started blowing again, sounds like a tank atm. Shoulda got a decent system the first time around I guess.
Not modified her in any way except for retro-fitting front fog lights and adding an alarm. Had a 2nd hand K&N induction kit on for a while but didn't like it.
So theres my experience with em.
