Tesco to sell cars? Well, every little helps

So, Tesco is going to sell cars. They will be delivered to buyers' homes in the same way the supermarket delivers groceries.
That'll be in a small box van then, for a £5 fee.
I look forward to the full might and culture of the supermarket experience being transferred to the struggling world of car retail.
Will there be two for one offers or will disgruntled customers simply be told to bog off?
Will there be club card points on cars and extra ones for people reusing their old models?
What will be the Tesco policy on free range vehicles like 4x4s? Coming soon, Hugh Fearnley Whittingstall on the scandal of the battery batteries.
Presumably there will be more then one specification in each range; finest, standard and value. Not forgetting the healthy organic option at a large premium.
When buying a car will punters be offered help with their packing and have the chance to donate small change to the local junior cricket club?
And most importantly; will Tesco undertake to open another road if more than two cars are queuing at the traffic lights?
