Here in Spain dealers have very little room to move on discounts as the profit margin they get from the manufacturer is very small. Traditionally in the UK margins were high allowing big dealer discounts although this may have changed since I last bought in the UK.
In Spain the deals are laid down by the manufacturer and can change on a monthly basis.
When I ordered my new Leon the total discounts came to about £5500 but some of that came from the government as I was disposing of a
Mk1 Leon over 10 years old. The dealer gives you €1200 and the government another €1000. It's all to do with getting old high emission cars off the road and also to stimulate the economy which is pretty dire in Spain at the moment.
There was then a €600 loyalty discount for owning a SEAT. Another €1000 towards extras and €2000 if you took out a finance agreement which also gave you an extra 2 year warranty.
Overall a pretty good deal.
They also do PCP deals just like the UK.
On balance I would rather be buying in the UK and have the chance for a good haggle - no chance here!
