1980 Nissan Skyline Additional Info:

1987 Nissan Skyline Project Vehicle
This is a 1987 Skyline GTS-X with a RB20DET "Red Top" Engine and 5 Speed transmission. This car has fairly low miles and the interior is decent.
Electronic gizmos were all the rage in the 80s and this car has them all. Things like folding mirrors, Adjustable lip spoiler and ECS shocks. The pictures show the true details of the car well. The wheels are Racing Hart 17s.
Lets get on to the issues this car has and why its being sold as a project.
1. The car does run and kinda drive but missfires above 3k and starts heating up if driven on the highway for long periods. Thats issue #1
2. Shocks are blown. This car had the factory ECS.
3. Cowl Rust. The cowl are and hood hinge area has some fairly bad rust. The rest of the chassis is nice, The cowl is just a common R31 spot.
"Paperwork"
First, Im in Texas. This car has never been registered, plated or titled in the US.I do not have a US title for the car. Here is what I do have-
NTSB/DOT Customs clearance where it came into the US legally and was imported legally under the 25 year law. I also have a copy of the Japanese title, I dont not have the original.
Payment must be made, in cash in full within a agreed upon time frame of no more than 7 days.
I will try and get a vid up of the car running
