Bought a Mercedes 240 CLK , 44k miles , not the dearest of cars but paid top price because of low mileage. Was offered warranty with national company or their own warranty for 3 months which I decided to go for , being a reputable firm decided this was best, no get out clauses where included, after 2 weeks exhaust was rattling , went back twice , approx. 70 mile each trip but they to busy to look at it. Third occasion I left car with them overnight, they gave me courtesy car to come home in.
