I went and test drove a 7 passenger Tribeca today, It has 50000 km about 30000 miles. It drove great though I did think the brakes were soft. I liked the exterior and especially the interior. I am concerned about having to use only premium gas and repair costs. Is there anything I should be looking for as far as problems etc. The dealer was asking 23000 cdn for a 2006 7 passenger and he also had a 2006 5 passenger for 19999 cdn with 67000km or about 42000 miles. Any suggestions or recommendations would be greatly appreciated.
