build cost

[alga]

If you're good at hunting for bargains in eBay, have most of the tools, have useful friends who can help, you can hope for around 3000 quid (including IVA).
If you're buying everything at list prices it works out at around £4000+IVA, and if you go for shiny high-spec items you could hit 5000.

The costliest items are bodywork (£500-ish for a 6-piece set, 900-ish for a full 10-piece), dampers (£300-400), IVA (£450), nice wheels (naught to £1000).
