I have a 93 Khyber, I took me months to find it and I have it for about two years now. And in this duration I have only done the basics nothing major. It is about how good the car car is when you are buying it.
When I bought her, she was and still is only on petrol, with recently changed suspension bushes and fluids. When I took her home, I changed all the fluids, took it to factory specs, repaired the AC, some small electrical issues, serviced the brakes and got new tyres that it nothing major. Costed me a bit more for a 93 but still working as a daily driver.
