For a unmodified 1989 car, I have tried to see the fastest it would go (like what I do with all cars). I got over 130 miles per hour with the CRX - and it still had a little more to go - this is excellent for a a car that is nearly 20 years old, and all I did was change the spark plugs and air filter.
I have thicker tyres (205/45) rather than the standard 185/65. When doing speeds over 100mph I would strongly recommend you put the thickest tyres on to offer better grip and handling.
I bought this car cos the shape reminds me of the car in back to the future. Also I owned a crappy 1996 Rover 25, which has to be the worst car I even owned. This car is still faster than brand new cars on the road today - especially in the 1000-1600cc range.
** Bad points **
Can be juicy in petrol if you put the pedal to the metal all of the time.
Insurance could be cheaper for a small car like this.
The car is a little flimsy - i.e plastic breaking inside etc.
