A solid TR6 can still be had for under 10K. The english ones were fuel injected and highly prized back in the day. A mechanic I knew converted his to FI and it was a significant improvement.

The TR250 was a gap/one year only car between the TR4 and the TR6 in 1968. The euro version was the TR5 which had fuel injection. The TR4A and the 250 look pretty similar with the main difference being the motor. The 4 had a 2 litre 4 and the 250 had a 2.5 litre 6 which would show up in the TR6 in 1969. The 250 is a rare car and probably expensive.

The TR6 is still plentiful on the west coast and an underappreciated bargain in my opinion. If I was to buy a Triumph today I'd look for a 69-73 model with overdrive. Due crash standards introduced in the states in 1974 the bumpers grew large ugly rubber pads and the turn signals got a separate housing. The early cars have a much cleaner look IMO.

The cars rust. Everywhere. I doubt that an unrestored, rust-free example exists. Fortunately you can buy any part you need from a number of suppliers. I have bought alot of bits from Moss Motors in Calif. Late in 1968 Triumph produced a competition preparation manual outlining steps to make the 250 and the 6 track-worthy. It covers engine mods, cooling, braking, wheels, suspension etc and is great guide to updating the car to a more modern standard.
