I am on my second Mercedes, this one is a diesel the previous one was petrol. Luckily there is a big red filler cap with diesel written on it. I also have a Smart car which my partner uses for work and I get to use now and again - cracking little motor and only £40 a year road tax
I agree with the comments about Mercedes servicing costs. The first service on mine was over £450!! If you go to a Mercedes main dealer they charge for engine oil by the 100ml - it works out at over £70 a gallon, absolutely outrageous
