What model car (probably American) is this?
OK here are some details to help you out: I saw this car in San Diego, California around 1989. I think it is an American car. It was black. It was probably at least a few years old at the time. I think it was 2 doors with a hatchback, but it may have had a trunk. Here’s the thing that may help you figure it out though. I think it had a letter and some numbers painted on it, like X-22 or something like that. I think it was 1 letter followed by 2 numbers. These numbers were also extremely large in size, probably close to 12 inches tall. I want to say it was a Chevrolet but I’m probably wrong on that. And the lettering wasn’t custom as far as I could tell, I think the car came stock that way. I’m pretty sure the lettering/numbering was the car’s model. Thank you in advance for any help you can provide.
if it was a chevy, could have been a citation x-11
