As a few of the guys here already have, I'd recommend you get a cheap-as-chips run around.
It will probably deepen your appreciation of the ethos of the Lotus and you'll begin to completely ignore the foibles..like they dont exist...!! It gives you such better perspective. Some of us young uns who spoilt themselves by getting one early having not driven that many other cars may relate to this
Having the additional runaround is relatively cheap...if you just drive it under the fully comp insurance of your Lotus, and you have an extra parking space. almost zero depreciation too! £50-100/year if you want!
Every time I see and sit in the Lotus now it it feels like such an event...
If your getting hassle from the wife, the runaround may help her appreciate it too!
Enjoy!
