Lighting

Demonstration of the Philips 4300K Xenon. This bulb puts out the most light at 3200 lumens. Normal halogen gives between 800 to 1200 lumens.Mega lighting on the road makes night driving safe. Comparision between halogen and HID on two Xantia.
Engine & Suspension
Engine runs sweet as it is so I didn't meddle anything there. I replaced most of the suspension components and upkeep the engine and transmission. Front suspension received all new components. Hydraulics system gets new spheres all around, Hydraflushed and renewed LHM and filters. Engine and gearbox gets regular oil and fluid changes.

Sorting out purchased Xantia parts in my store. Yes I hoard spare parts. All the fittings, rods and bushes needed for the front suspension.

Parts galore.! Also plenty of filters, oils and fluids for couple of years of services.
Exterior
The paint is still lovely so I just keep it clean, polished and waxed. Car is groomed with Zymol and Swissol stuff mostly. Plastic bits gets fed with Solar Warrior; my favourite plastic protectant.
Windows were not tinted so I decided to change all to new glasses before tinting. Sekurit glasses on doors and Soliver windscreen. Light brown tint gives a smoked tone when matched with the already tinted glasses.

Silver trims around the front and rear bumpers and on door protectors were weather beaten and faded over the years. Purchased new trims from Citroen.
Car is rolling on Citroen Magny-Cours wheels wrapped with Michelin Pilot Precedas.

Wheels polished and waxed to silky smooth touch. Bibendum makes great mates with Citroens.
