“VAT free” is an obfuscation. You get a discount equivalent to VAT not being applied, which works out at 16.67 per cent including VAT. But now that the old model SX4 is being replaced by both a new SX4 and the bigger SX4 S-Cross, that's all the car is worth. Its depreciation will be from the reduced price, not the original list price. That said, it's quite a good car, particularly the 1.6 petrol. So buy it on its merits compared to other cars, and aim to keep it for a long time.
