looking for an X19.

I'm looking for an X19.
I last owned and drove a blue one in 1988 but unfortunately I bought it with quite a lot of rust and over time it rusted away underneath me! but I owned the car for a few years and loved it, albeit being 6 foot tall! The colour was a medium blue, not a dark navy nor a sky blue, Does anyone know the likely colour or reference No?

I would love to find another X19.
Anyway I am keeping a close eye on the various websites for a good value buy and hopefully little rust if that's possible after all these years??
Budget around £3k to £4k at a stretch for the right car.
