I used mine as a daily driver for just over a year, then I parked it up to move back to America. It was needing a gear box, which it is actually getting repaired now.
In my year of daily driver, I replaced the brake and clutch master cylinder, I had to replace a fuse for the starter and I had the seals on my brakes need replaced.
I managed to change these things on my own as well, so it depends a lot on who will do the work if the car breaks, because for me that was a major part of my reason for using it every day. If I didn't have the time, resources or skills (very limited) to change these things on my own, I wouldn't have used it everyday. It was more a price thing for me.
However, like I said, mines is in getting a replacement gearbox now.
If you were hoping to use it on the track and the strip, I would not rely on it being a daily driver. The harder you push the car, the more problems you are going to experience. Apart from the occasional blast off of a roundabout and a couple of B road blasts, I honestly don't kick the crap out of my car.
There are so many factors you have to take into consideration.
I feel like I have been lucky with mine, knowing some of the horror stories ther owners have had.
Imho. If you are going to put in time changing simple parts and don't kick the arse out of it everywhere you go, then you probably will be able to drive it every day with not to many problems.
If you are hoping to track it and put it on th strip, you are going to find it more difficult to have a daily driver.
Hope that helps.
