I bought a 2nd hand Audi A6 114,000 mls Non Main Dealer

Should have gone the main dealer route :-
It did have an RAC (Reject All Claims) warranty but :-
1) Leaking Steering rack - replaced by Shi....r dealer - took 2 weeks, damaged the Wing and it leaked again after a few days
(Took it to Lincoln main dealer fixed in a Day £££ no problems for next 7 years to 245,000mls)
2) Thought

Better have cam belt changed as couldn't trace last change - Turned out the engine had dropped a valve at 22,000mls & a bodge job was done meanwhile Shi..r dealer had changed hands! sorry none of our business mate!
Main dealer fixed it but needed 5 pairs of cam followers (£500+) Camshaft etc...£2k+ (ouch)
this would have been covered by the Main dealer warranty, but obviously wasn't by RAC
So My new Volvo (hope it's as reliable as the 944Turbo has been) is from a main Dealer, I would be very reluctant to go elsewhere
(Although did have a bad experience with a VW Main Dealer (Stork or something like that! - also did Audis) when the cam belt needed changing again, after they had done it it slipped a tooth the next morning on way past their garage, fortunately no damage - they FIXED it but after travelling 200 miles to Cardiff I found a socket wrench, Cambelt cover and retaining bolt in the rear tray under the bonnet. What a load of ....
Is it all worth it I wonder
