nope wait a little if it has some problems it'll come out in about some months when other people buy the vehicle most cars dont have any problems but if you just wait a little you might get the same vehicle in a lower price =P
Well there will be problems with newer vehicles. So don't buy it when you first hear about it. Wait 3 or 4 months and check the manufactures web site for any info that all the bugs have been fixed. Then you can buy the car.
