Historical MOT pass rates and DVLA records for 2004 model year cars.
- Front Chassis Rail CorrosionSerious
NB cars can rust badly inside the front chassis rails, sometimes while the outer structure still looks respectable from above.
- Rear Sill and Arch RustSerious
Like the NA, the NB traps moisture around the rear sill sections and arch returns, so rot often starts where it is easy to hide with cosmetic repairs.
- Blocked Hood Drains and Cabin DampModerate
When the soft-top drains block, water can back up into the cabin and accelerate rust in the sills and floor area.
