We have a couple of the digital speed indicators along the roads here where
I checked my speed a couple of times. Both my 80 and 90q were pretty
accurate up until quite high speeds. There must be some discrepancy at high
speeds though- I had my 80 1.8 up to 125 mph once- far higher than its
official top speed. The 80 had original-size tyres, while the 90 has
195/50s instead of the proper 195/55s.
The Daewoo Leganza 2.2 I'd rented for my recent tour of the SW US was
optimistic by about 5mph @ 65. VERY accurate below that- verified by the
digital speed indicators again.
