be aware, the Honda Civic in the Workshop is not the correct car for S397 BTCC events. Only the DLC cars in the STORE will meet the criteria. You only need to purchase one car out of the pack, but you will need one official car if you want to take part in any online activities.YES! I found an appropriate Honda Civic & several tracks on steam workshop (listed above).
One of them is Knockhill, but I haven't run it yet...
Offline? Not a problem, any car will do.
