Well after much deliberation i've decided to repair the car. Looking around theres nothing else that I fancy. The car will be recorded as a total loss (uneconomic repair) but that won't matter as i'll never sell it. BUT i'll get lots of photos showing various stages of the repair to put with the history to show its been done properly.
Its going to cost me £2100 for the bodywork, plus a wheel refurb to repair the one scraped wheel caused by crash.
Hopefully she'll be back to her former glory in next few weeks. Won't get used much as i've got a R plate Astra as my everyday car now, so should keep the mileage and condition spot on.
