The MGB GT went to Peter Satori on July 14, 1970 for its’ 18,000 mile service. Mileage at the time was 18,796. The standard service involved changing engine oil and transmission oil but little parts were breaking. The left inner door handle release was replaced, cost all of $1.69, and the intermittent tachometer was repaired. I get the feeling that these tachs aren’t very dependable in fact it still has issues at 132,000 miles!
Total cost of the service was $43.05.
