I had a Volvo XC70 SE Lux AWD Auto.
This was a very good car to drive, but it had lots of small problems over the three years I had it. Probably had to go back to the dealer at least 3 or 4 times a year.
Even on the day I picked it up from the dealer, I found a number of faults. The AC wasn't working, Some of the windows didn't go up and down correctly, The fuel gauge only showed half a tank when the tank was full. There were many more things like this over the time I had it.
It was faster than the Antara and it had better acceleration. The seats on the Antara are better and provide more sideways support when you go round a corner fast. Only thing I miss about the Volvo seats is they were ventilated and gave you a nice cool bum in the summer when/if it gets warm.
Although my Volvo is a much more expensive car than the Antara, I think the Antara is an all round better car for me.
