I thought it looked pretty solid. It's not the fastest thing out there, but it's not the slowest. STR will benefit from upgrades when they return to Europe, so the early races will be all about taking advantage of the mistakes of others. A wet qualifying really gives them a good shot to move up the grid, too.
The team has already said that 2013 isn't their main focus this year. They're really looking ahead to 2014 and are preparing well in advance for it. Unfortunately that means that they're unlikely to make much progress up the field this season, but it should still provide their drivers with the opportunity to get some decent points. The STR7 wasn't that great, yet Ricciardo managed to set the sixth fastest lap in Bahrain (which was stunning, thinking about it). Now that both of the drivers have matured and know just what to do during a race weekend and the race itself, I'll be expecting some solid results.
Don't write the whole season off after the first two practice sessions of the first race of a 19 race season.
true dan said that they just need to work on the set up but its not looking promising, they were crap enough last year
