Importing a car from the US, I did do a write up on this, it was a sticky or FAQ on importing on here before.
Basically allow a couple of grand plus the taxes.
Shipping is only part of the cost.
You need to get it from where ever it is to the dock - bank on $1 per mile. Get paperwork presented. Pay for loading, dock side fees, storage, maritime insurance (optional), stevedores bribes and so on. Then on the boat (shipping) then unloading, customs fees, paperwork presentation fee, then tax, duty, storage and transport home.
Remember VAT is usually due on the cost of the shipping as well. So a grands worth of freight becomes £1200 due to VAT.
Once you get it fixed up well enough to drive, you need to convert the lights to UK spec, get an MOT, and the DVLA will want you to pay to register it.
Older cars (over 30 years) seem to be fairly easy to get the reduced rate of import taxes at the moment but they periodically tighten up on that.
OT - Good to see you back :-)
