Im found an automatic Pontiac sunfire 1999 convertible online and I am considering buying it.

When I met my wife, she owned the turbo version of your car but not the convertible. When we traded it in for a new car in 2008, the best trade-in value we could get for it was $1,250.00 usd with a retail value of $1,600.00. The body was fine, but it had 142,000 miles on it, which seriously affected the value. As a 16 year old car now, at 2750 usd, I would avoid purchasing and find another vehicle. If you insist on buying it, make sure your small, friend-filled road trip extends no further than the neighborhood grocery store. You didn't say who performed the repairs or whether they are warranted or how long the warranty lasts, but my rule of thumb is that any repairs are only as good as your knowledge and trust in whoever performed them. Hope this information was useful.

Probably not a good idea.

Although 240000km = 149129mi, the price is still well above a reasonable value. Also, the mention of snow/road salt in Canada over sixteen years, rust would be a concern. I agree that this car should be bypassed.
