Weigh the ups and downs before buying.

I have driven this car for 10 years. It was in and out of the shop constantly after I bought it and it is an expensive car to fix. I had to rebuild the engine in 2013. Ever since the vehicle has driven great. It is a smooth ride and feels good on the road. Aside from the expensive repairs, I really like the vehicle.

It is red and nice and fun to drive it has lights and trunk to store stuff.

It is nice and cool and fun to drive and comfy. It is fast when I want it to be and can be very good vehicle in the snow as well it seems to get the job done when needing to. The car is red and has nice lights it never needs an oil change its always up to date it never has anything that is not up to date.
