Lets assume the following. First, each building will remain hardwired. Second, there is a router of some kind with one vacant port in each building. And third, the car dealership network can get by for the next several years on 11-Mbps bandwidth between the buildings.
With these assumptions in mind, I would recommend two 2.4-GHz BreezeNet DS.11 outdoor wireless bridges from Breezecom (now merged with Floware to become "Alvarion"), and their antennas.
This solution would cost approximately $3,000 to $4,000 for hardware if purchased new, but there is a ton of this stuff (hardly used) available on eBay or other auction sites, which could bring the equipment costs below $1,000. Installation and network IT services to set it up should not exceed a half-day and $600.
If the dealership can make due with less bandwidth (say, 1.5 Mbps to 2 Mbps), I would instead recommend two 2.4-GHz BreezeLINK E1 wireless bridges and antennas from Alvarion.
The equipment (if purchased new) costs approximately $2,400 to $3,000, or less than $1,000 if bought used. Installation and integration would cost the same as above.
All of this gear is pretty much bulletproof once properly installed and set up, and provides ample data throughput and security for most small or midsize businesses. Also, future capacity expansion is easily accomplished by adding additional bridges; and they can accommodate voice, data, fax and video traffic in the event the dealership eventually opts to merge its voice and data networks.
As a backup, the easiest solution would be the same type of bridge on a different part of the building.
The redundant "backup" bridge could be configured to work in tandem with the main bridge during most periods (thereby supplying more throughput). And if one link goes down, all of the traffic can fail over to the other link.
If redundancy is really a vital concern, Id recommend a wireless link on a different frequency, such as 5.8 GHz. Two solutions come to mind: RadioLANs Campus BridgeLink 347 or Western Multiplexs 12-Mbps Tsunami 5.8 GHz 10BaseT.
Still, these devices are overkill for this solution because they can handle much greater distances and bandwidth than required here.
The 5.8-GHz solution would cost $4,000 to $6,000 new, with auction, bankruptcy or reconditioned gear costing about $1,500-$3,000. Costs for install and integration would be about the same as for the 2.4-GHz gear described above.
All of the 5.8-GHz and 2.4-GHz gear comes with easy-to-use Web-based management software.
