2019 Jap Import advice

[Wyley]

Been in the market for an import for a while now and am quite set on an S15 Spec-R or PS13. I am in the UK and see that Torque GT would be my best option to manage the import, but they require a budget from myself. What should I be expecting to pay for each car including the fee's which Torque would take for it to be on the UK roads? I'm looking for a grade 4+ with as little mods as possible.

I'd also appreciate any buying advise as I have no idea what goes in to the import process.
