Not sure if I imagined it, but do Skoda dealers in UK offer a package deal on services (like VW and Mini)so for example, you pay £300 and get 3 years servicing (labour and parts...?

Yes - they did do a 2yr/20k mile package at £299 last year; they threw in £100 vouchers too.

I opted for it on my Octavia vRS; not sure if its still being sold though - check with your local dealer.

I got free servicing included FOC with my Superb, nice little bonus , its going in for its last (30K) service next week

Yes: Just call in to your dealer and they will quote you.
