Lotus Soft Top Refurb Service
Contact: Mel Broome, Lotus Cars - 01953 608153 (aftersales team)
Service includes:
- Light cleaning
- Replacement of front plastic strip
- Replacement of rear elastics
- Re-stitching where necessary / worn etc
- Optionally - new rear tensioner cable installed (see prices below)
- Standard refurb £77.98
- Including new rear tensioner cable £209.95
For comparison, new hood costs £667.48
Logistics:
- Must be booked in and shipped from a franchised Lotus dealer
- generally 1 week turnaround
Now it's probable that you can source the tensioner cable etc and have a go at fitting yourself but I think some fettling and welding is involved, so for the sake of a job done once every few years only, I know I'd leave it to the Professionals

A relative used this service last year and the result was excellent.
However if your elastics, tensioner and stitching are in good shape, then a simple DIY soft top rejuvenation is all you need, details here:
