I have had my r129 since 2008 and have driven about 80k miles. Daily driver for first 10 years and since then lowered mileage. Main issues I have had apart from servicing
- ASR light and resolved by replacing basic module (twice). It stranded me once and had to be towed home
- Maf sensor replaced because of idle hunting
- soft top needs replacing. In progress as we speak
- front fenders replaced and now a bit rusty again
- I think suspension could do with new shocks and springs
- ac evaporator is leaking so need to replace (dashboard out project)
- had electrical issue with wiper and Indicator light and replaced relay which did not fix it. Removed wiper motor and cleaned it and greased it as well as the stalk on the steering wheel and issue seems to fixed but as the issue was intermittent time will tell and I dont drive It as much as I used to
- exhaust is rusty and squeaking so will replace soon as well
Apart from that all good and love driving it and despite the long list above it is expected after alll these years and miles. I reckon after those repairs it will be good for another 20 years
