I have always owned run of the mill cars, my last two being Mondeo's but now I have ordered a C200 sport petrol automatic. Decision 1/ I always pay cash and ideally keep cars for around 5 years but Mercedies are doing an offer if the car was bought with finance. I went via a broker but the dealer salesman I was put in touch with wanted me to buy the car through a PCP while I wanted an HP loan of £3000 borrowed over 2 years to minimize the interest payments. He put up a fight so lost the sale. Another broker put me in touch with the same dealer but a different salesman and the deal was done with no problems until the first salesman found out what had happened but it was tough on him. Decision 2/ Colour to be tenorite grey with crystal grey upholstery and the upgraded stereo. The Worries Will the running costs keep me poor, as I have read that main dealer service rates are eye watering and the car is much more expensive to service than my Mondeo? I read that I can do a service plan for £30 per month but I was wondering would it be cheaper to just pay for the first A service and then start paying £30 per month so I get two B services and one A service for my monthly payment? Should I have got the car on a 3 year PCP and then handed it back and maybe bought a second one? My intention is to keep this one 6 years to reduce the average depreciation per year in the hope that one car over 6 years with added maintenance costs is cheaper than 2 cars under warranty over the same period. As for annual mileage it should be around 6,000 per year so the car at 6 years should have done around 36,000 miles. Should I take out an extended warranty or with that sort of mileage should I take a chance bearing in mind the car will be kept for 6 years. Finally I have gone for the crystal grey upholstery except just the seats and upper door cards will be this colour while the rest of the interior will be black. I would have preferred if most of the interior was the same colour like the beige option so I am wondering will the interior look odd? So why did I not go for the standard black? I didn't fancy getting burned on a hot sunny summers when the car has been left in the sun all day. Anyway a little about me. I am 58 and have retired , got a wife and a couple of grown up kids that live at home plus a small dog. No doubt I will be coming to this forum many times over the next 6 years so I look forward to ever ones opinion.
