My astra is starting to show, and feel, it's age. 8 years old and coming up to 98,000 miles. It needs a new oil pickup seal, which involves taking various bits off and dropping the sump (to replace a £25 seal). The prices I've seen on various forums range from £300 to £400 to a sharp intake and flat refusal. It's giving me a 'service vehicle soon' on startup, which means it needs one (or, possibly, more) glow plugs at £120 a pop. MOT and service are coming up in three months. It's tatty. My fault for not getting scratches and scrapes done as soon as they occurred. Both front doors from car parks and front bumper both sides from me being gozzy. Had a quote last year from a well recommended local lad for £450, but I've added another door since then.
Under normal circumstances, it would be down to WBAC, and me accepting whatever they offered. But used car prices are still way too high for what you actually get. So, as I say, decision time soon.
