I know it's impossible to answer really and going to be biased on here but as a long-time member (10 years!) but relatively quiet recent user of the forum I though I'd put it out there....
Beloved 1.9 GT TDI 130 has just passed 250,000
It's also just developed a brake problem with a £400 part (servo) needed.
Turbo is on the way out (got a quote from trusted garage for around £600 all in)
Timing belt due in 6k (about 3/4 months)
Radiator leaking (slightly - been doing for a while) and could probably DIY so just parts cost)
Minor bits - rear hatch lock dodgy/no boot light, door locks sticking, passenger window reg sounds rough
I love the car (had since 70k) and want to keep it ideally as know my way around and do all regular maintenance myself. Got my set of winter wheels as well and been well loved over the years. Done minor cosmetic "mods" - Recaro rears, debadging, wipers, aerial etc... but £1500 on a 20 year old car seems mad and I think the garage owner agrees.
He said the new brake part could put pressure elsewhere in the system and cause problems but don't know what you guys think?
Comes down to:
a) replace the brakes and hope the turbo holds on (currently rattling when take foot off gas but has been for ages) as well as TBelt and just get another few months out of the old boy
b - do the full lot!
c) break (it'll sit on my drive and have parts sent away over the next 6 months)
