Hi Jay,
I have also just picked up a Brechin Slate/Oakham RX300 although i managed to get the SEL.
I only had the exterior supaguarded as the interior apparently becomes a dust magnet if treated.............
I also had the protective film fitted to the rear bumper for £69.
Retro fits are v expensive - I wanted a wood pack and they wanted £186 for a wood gear knob and around £2000 the change the steering wheel! In the end after talking to Lexus UK I got the wooden gear knob for £65.
Oakham mats are hard to keep clean and u should either but a plastic covering for the winter months or spare mats.
Boot liner is around £84.
The reversing camera is standard on the SE model! What you miss is the air suspension, fantastic levinson sound system and adaptive front lighting
Additional Features on RX300 SE
18 inch alloy wheels with locking wheel nuts
Leather upholstery
Power operated tailgate
Electrchromic rear view mirrors (automatic anti-glare)
Heated front seats
Electric one-touch tilt and slide sunroof with anti-jam protection
40/20/40 foldable rear seat
Rain sensitive windscreen wipers
Memory package for steering wheel, mirror and drivers seat
Optional DVD-based touch-screen Lexus Navigator system with rear view camera
Happy driving mate and welcome to the club!
