We've been driving only the B180D automatic for 9 years — there's nothing better. Great on long trips; the next one will be another B180D automatic.

My wife and I have been driving a Mercedes W247 200d for seven years now, with 93,000 km on the clock. The car is very comfortable even on long trips and economical. At the last service the pads of the electric parking brake were replaced; otherwise no repairs. We love this car.

I won a Dacia Duster in a lottery. Sold it after six months. Just cheap junk. Then the XC90/1 and now the XC90/2. There are galaxies between them. A Volvo is a Volvo when it comes to reliability, durability and luxury.

I drive both cars. The XC90’s boot is — contrary to the figures posted here — noticeably larger than the GLC’s when carrying five people. Overall the XC90 is clearly the more comfortable and, above all, the more stable — and therefore the safer — car.
