Xenons were never an option on the Mk1 Seat Leon.I think the ST220 is easily the best option there. I wish things like the Civic Type R saloon had been around longer and were more popular, because I think they look awesome.
The LCR is just a leon with a quicker engine. Absolutely no extras, with the exception of Xenons. The interior is exactly the same as my SE derv leon.
Options that did exist were heated seats, electric seats, leather seats, recaros, cruise control, auto dimming mirrors, electric folding mirrors, etc etc.
Not quite sure what you're on about there. Surely the interior of an ST220 will be mighty similar to a 1.8LX?
