With a tax-free car costing around £20,000 there would be £4000 VAT to add if buying tax-paid.
However, if you take into account the cost of shipping a car to and from Cyprus, plus the additional cost of Cyprus registration, there's very little difference between the tax-free and tax-paid overall prices.
So let us know the make and model and we'll get you prices for both tax-free and tax-paid, if you are undecided.
