Last summer I put 7,000 miles on my 95 MGF without an incident. This included three long drives:
- Weekend trip to Virginia with a total distance 1,000 miles, including 500 miles in one day.
- Weekend trip to Indiana and Kentucky with a total distance of 1,200 miles.
- Visiting my parents in New Brunswick: total distance of 2,100 miles, inculding 750 miles in one day.
So, drive your car on a long trip, it will be fine. And if you do have a problem, don't worry about it, you can get your car serviced if you have a problem. At least your local garages know what an MGF is.
