It looks very clean and tidy but possibly superficial. To me it looks like the wheels, brake discs, callipers and wheel arches have all be recently sprayed (to cover up corrosion), but was it done properly? Certainly the wheels have just been sprayed with an aerosol rather than being properly refurbished (you can see the overspray on the tyres) so the finish might not last that long.
These vehicles, at this age, are prone to corrosion on the sills and underneath - you want to make sure this metalwork is sound, not just had a layer of underseal sprayed over corrosion.
These RX are also now prone to water ingress due to failing body seams and rear light seals - check the boot well for any water.
Price seems high, but it is low mileage. Personally I'd prefer a newer vehicle with more miles as age is the bigger issue.
